The Meeting of Parties to the Cartagena Protocol in Hyderabad has been discussing safety issues pertaining to living modified organisms for the past two days. Experts warned that there are possibilities of new viruses arising through recombination of the naturally-occurring relatives of genetically modified vaccines in the same ecosystem. It may be recalled that in clinical trails in 2010, four girls died in Khammam district after they were given the Human Papilloma Virus vaccine, a recombinant DNA-based vaccine to prevent cervical cancer. Prof. Terje Traavik of the Centre for Biosafety in Norway said that his study found ”many first-generation live, genetically-engineered vaccines are inherently unpredictable, possibly dangerous and their use should not be widespread until all issues are clarified.”
